Description
Technical field
The utility model relates to computing machine human body input equipment, particularly relates to a kind of portable computer keyboard.
Background technology
Along with popularizing fast of computing machine, nowadays very familiar concerning people as the computer keyboard of computing machine human body input equipment.
As everyone knows, numerical key in computer keyboard in occupation of indispensable status.In modal computer keyboard, letter key top and the keyboard rightmost side are respectively equipped with numerical key, the numerical key of letter key top is layout type in one line, inputs a large amount of very inconvenience when digital, and affect very much input speed and accuracy rate at needs; Be positioned at separately a region although be arranged in the numerical key of the keyboard rightmost side, for concentrating input numeral that convenience is provided, but in the time running into letter and number and combine more situation, distant due between letter key and numerical key, the switching of operator between the two is also very inconvenient.
Between letter key and numerical key, switch inconvenient problem in order to solve operator, there is on the market a kind of computer keyboard that numerical key is arranged in to keyboard centre, obviously, this arrangement has reduced the distance between letter key and numerical key, in the process using, the problems referred to above are also really solved to a certain extent, and because the letter key of keyboard just had the division of left-handed operation key and right-hand operated key originally, after numerical key is placed in to keyboard centre, can also play the effect that increases left-handed operation key and right-hand operated key spacing, also be more conducive to the ergonomics mode development of keyboard.
But, development of computer so far, portable computer, dull and stereotyped PC and Radio Transmission Technology etc. have all obtained significant progress, particularly for portable computer, it is directly integrated in computing machine itself by keyboard often, and concerning dull and stereotyped PC, itself is not with hardware keyboards, although portable, produce accordingly also inconvenience.This has just proposed new requirement to keyboard---and portable! Above-mentioned is only obviously not possess portable characteristic by adjusting the keyboard of key mapping during numerical key is put.
Summary of the invention
The purpose of this utility model is to provide a kind of portable computer keyboard easy to use.
In order to address the above problem, portable computer keyboard of the present utility model is by the following technical solutions: portable computer keyboard, comprise left-handed operation key, right-hand operated key and numerical key, described left-handed operation key and right-hand operated key are located on a top layer panel, top layer panel is spliced by left and right two parts, left-handed operation key and right-hand operated key are divided in two parts of top layer panel, numerical key is located on a bottom panel, at least one in two parts of top layer panel coordinates with bottom panel guiding anticreep along left and right directions, bottom panel and numerical key are covered by top layer panel in the time that two parts of top layer panel are stitched together, in the time that separating, expose two parts of top layer panel.
Between bottom panel and part top layer panel and that its guiding anticreep coordinates, be provided with driving mechanism.
One in described bottom panel and top layer panel is provided with gear and drive unit, and another is provided with the tooth bar engaging with gear, and drive unit, gear form described driving mechanism together with tooth bar.
Between described bottom panel and top layer panel, be provided with position-limit mechanism.
Described position-limit mechanism comprise left and right be relatively located on tooth bar, be that splayed distributes two dial bar and between two groups of bars, can dial the movable block that move forward and backward under bar effect, movable block is connected with the limit switch of controlling driving mechanism start and stop by push rod.
Described driving mechanism is motor.
On this keyboard, be also provided with the shift knob for controlling motor.
Because left-handed operation key and the right-hand operated key of this portable computer keyboard are divided in two parts of top layer panel, numerical key is located on a bottom panel, at least one in two parts of top layer panel coordinates with bottom panel guiding anticreep along left and right directions, bottom panel and numerical key are covered by top layer panel in the time that two parts of top layer panel are stitched together, in the time that separating, expose two parts of top layer panel, therefore, when in use, can numeric keypad be exposed by the appropriate section of movable top deck panels, thereby handled easily person's use, because numerical key is the position between two parts of top layer panel, also reached the effect that more meets ergonomics, improve the comfortableness of operation, when not in use, dwindle the size of keyboard itself by making two parts amalgamation of top layer panel, thereby can reach portable object.
Further, driving mechanism contributes to realize automatic deciliter of top layer panel, makes the use of keyboard convenient; Gear-rack drive mechanism structure is simple and be easy to control; Position-limit mechanism can limit the shift motion of top layer panel appropriate section effectively, prevents from moving the excessive keyboard that damages because of it.
Brief description of the drawings
Fig. 1 is the embodiment of the portable computer keyboard structural representation in the time of top layer panel splicing;
Fig. 2 is the embodiment of the portable computer keyboard structural representation in the time that top layer panel separates;
Fig. 3 is driving mechanism and the schematic diagram that coordinates of top, bottom panel.
Embodiment
The embodiment of portable computer keyboard, as Figure 1-3, this portable computer keyboard comprises top layer panel 11 and bottom panel 12, and what top layer panel 11 adopted is split-type structural, and it is spliced by left-half and right half part.The left-handed operation key of keyboard is located in the left-half of top layer panel 11, and right-hand operated key is located on the right half part of top layer panel 11, and numerical key is located on bottom panel 12.
